Google Pay activation issues
Mastercard are currently experiencing a few issues with activating some cards for Google Pay that are beyond our control. Their engineers are looking into this, but unfortunately we don’t have a timescale for the fix just yet.
In the meantime, please try the following steps which have resolved the issues for some people:
Remove your card from your Google Pay completely
Force Close the Monzo app
Open the Monzo app and tap ‘Manage’ to the right of your transaction feed
Tap on Add to GPay and follow the steps to add your card to Google Pay
Thank you for your patience here!
